LAMP.

SPECIFICATION forming part of Letters Patent No. l712,071, dated October28, 1902.

Application iiled June 12, 1902. Serial No. 111,337. (No model.) Y

To all whom it 17m/y concern:

Be it known that I, MANANDER M. JOHNSON, a citizen of the United States,residing at Clay Center, in the county of Clay and State of Nebraska,have invented certain new and useful Improvements in Lamps; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to lamps, and particularly to oil-burning lampsof the character designed more especially for use in connection withincubators.

The object of the invention is to provide a lamp of this character inwhich provision is made for keeping the oil-font cool and permitting ofthe escapeof any gases generated therein, thereby obviating allliability of the gases being generated and confined tO such an extent asto cause an explosion.

With these and other objects in view the invention consists in certainnovel features of construction, combination, and arrangement of parts,which will be hereinafter more fully set forth, and particularly definedin the appended claim.

The figure of the drawing represents a central vertical section of alampembodying my invention.

Referring to the drawing, the numeral l represents a metallic bowl orfont provided in its top with a central opening 2, and 3 is an annularwater reservoir superposed upon said bowl and having a central tube 4coinciding with said Opening. A collar 5, mounted upon the reservoir, isthreaded to receive the burner 6, which maybe of any ordinaryconstruction. The reservoir is su pplied with water and forms a jacketinclosing the burner to keep the bowl cool and reduce to a minimum theamount of gas generated from the heat of the lamp.

Extending upwardly through the bottom of the font and terminatingadjacent t the cOllar 5 is an air-tube 7, through which air is admittedtO further cool the burner. This air discharges through a vent formed bya handle 8, which is provided with the tubular legs 9 and 10, onecommunicating with the font and the other with lthe water-jacket. Bythis means the gas generated in the font is allowed to discharge, andall vapor formed in the water-jacket is also allowed to pass off. Thetubes 9 and 10 further form funnels through which the oil-reservoir andjacket may be conveniently lled.

It will be seen that owing to the fact that the font is kept cool theformation of gas is reduced to the minimum, and that what little gasthat is permitted to form is carried off through ther Vent by the airfrom tube 7, thereby' obvi'ating all liability of an eXplosion. v

I-Iaving thus described my invention, wha I claim as new, and desire tosecure by Letters Patent, is

A lamp, comprising a bowl provided with an Opening in its top, aburner-supporting tube rising from said opening, a water-reservoirsuperposed upon the bowl and surrounding said burner-supporting tube, anair-supply tube leading to the interior of the burnersupporting tube,and a handle having tubular legs forming vents and funnels, onecommunicating with the bowl and the other with the water reservoir,substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.

MANANDER M. JOHNSON.
